براغي رأس مقبس M10-1.5 × 100 مم | محرك سداسي | خيط جزئي | فولاذ سبائكي فئة 8.8 مع أكسيد أسود حراري (50/عبوة)

I needed extra length for a jig I'm building, and these 100mm screws fit the bill perfectly with a clean, precise thread all the way. The black oxide finish feels durable and hasn't flaked during tightening, which is a huge plus for these applications.

The hex socket drive grabbed my hex key perfectly without any slippage. Exactly 100mm as described, and the black oxide finish gives them a clean, professional look. These will be perfect for my precision tooling project.

The black oxide finish on these M10 screws resisted scratches during assembly, and the hex drive seated perfectly with my Allen key. For building precision tooling, the partial threading gives just the right grip depth.
